Option c is different from others. Because in (c) we get a positive integer as answer i.e., +5.
(a)20+(-25)=20-25=-5
(b)-37+32=-5
(c)-5*-1=+5
(d)( 45 ) ÷ ( – 9)=-5
0

I)20+(-25)=20-25= -5................................. ii) (-37)-(-32) =-37+32= -5........................................... iii) (-5)×(-1)= +5.................................... iv) 45÷(-9)= -5............... Since the answers of (i), (ii) and (iv) is -5 and the answer of (iii) is +5..... So C or (iii) is different from others.
